Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y=a(x-h)^2+k[/tex]

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

The graph provided in the question, assumed as a parabola, has two clear points:

The vertex, located at (-2,-3)

The point (-1,-6)

Substituting the coordinates of the vertex, the equation of the function is:

[tex]y=a(x-(-2))^2-3[/tex]

[tex]y=a(x+2)^2-3[/tex]

The value of a will be determined by using the other point (-1,-6):

[tex]-6=a(-1+2)^2-3[/tex]

Operating:

[tex]-6=a(1)-3[/tex]

Solving:

a=-3

The equation of the graph is:

[tex]\boxed{y=-3(x+2)^2-3}[/tex]

Answer:

(43 - 56) + 13 = 0 points

Step-by-step explanation:

We start with 43 points and loose 56 -- 43-56

then, 13 points are gained = (43 - 56) + 13

simplify and solve:

-13 + 13 = 0

*Note: you can write the expression without the brackets

Answer:

11.34

Step-by-step explanation:

I hope this helps!

Step-by-step explanation:

Sum of −8.46 and 5.31 means we need to add −8.46+5.31.

We know that,

|-8.46| > |5.31|

It means we subtract 8.46 - 5.31

At hundredth place, 6-1 = 5

At tenths place, 4-3 = 1

At ones place, 8-5 = 3

It would mean that, 8.46 - 5.31 = 3.15

8.46 has a negative sign. It means that the final answer will have negative sign i.e. −8.46+5.31 = -3.15

Hence, the correct option is (a) " Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is negative".

Randi earn $24,300 next year.

Here,

Given that;

Two years ago Randi earned $18,400. last year she earned $19,700.

And, she earns $21,600 this year.

The average of four year is $21,000

We have to find, the amount she earn in next year.

What is Average?

A number that is calculated by adding quantities together and dividing the total by the number of quantities.

Now,

Let she earn $ x in next year.

The average of four year is $21,000.

Hence, Average of money for four year is;

[tex]\frac{18,400+19,700+21,600+x}{4} = 21,000[/tex]

[tex]59,700 + x = 84,000[/tex]

[tex]x = 24,300[/tex]

So, She earn $24,300 in next year.

The distance between the two points is 4

Step-by-step explanation:

(8, -1) - (4, -1) is 4, so I’d say the answer is four.

Answer:

4

Step-by-step explanation:

Step-by-step explanation:

Length = x

Width = (x-5)

Perimeter = 2 lengths + 2 widths

50 ft = x + x + (x-5) + (x-5)

50 ft = 4x - 10

60 ft = 4x

15 ft = x

length = x = 15 ft

width = (x-5) = (15 -5) = 10 ft

dimensions = length × width

= 15 ft × 10 ft

if you wanna check,

50 ft = x + x + (x-5) + (x-5)

50 ft = 15 + 15 + (15-5) + (15-5)

50 ft = 30 +(10+10)

50 ft = 30 + 20

50 ft = 50

Answer:

.95 per cup

Step-by-step explanation:

There are 4 cups per quart.

But this is 2 quarts so we are using 8.

divide 7.28/8  is .9475

Let's see what to do buddy...

_________________________________ Step (1)

First we must find the measure of x

[tex](3x - 5) + (x + 1) = 180[/tex]

[tex]4x - 4 = 180[/tex]

Both sides plus 4

[tex]4x = 184[/tex]

Divided both sides by 4

[tex]x = \frac{184}{4} \\ [/tex]

[tex]x = 46[/tex]

_________________________________

Step (2)

Now we must find the RQS Angle measure :

Angle ( RQS ) = 46 + 1 = 47

_________________________________

Step (3)

QT bisects RQS ;

So the resulting angles are :

[tex] \frac{47}{2} = 23.5 \\ [/tex]

And we're done.

Thanks for watching buddy good luck.
